Description

one

The invention is intended to integrate non-inmate signals and can be used in pneumatic automation systems and computer technology when pneumatics are used in combination with electrical elements.

The known non-electrical integrating device containing a pneumatic electrophoreses, made of a chamber connected to an input channel in which two electrodes are installed, the first of which is connected to a high voltage source and the second through a load resistor with a measuring unit, has a narrow resolution and narrow frequency band integration.

The purpose of the invention is to increase the resolution and expansion of frequency dianasoia.

This is achieved by the fact that a second pneumo-electric converter is installed in the device, the chamber of which through the capillary tube is connected to the chamber of the first pneumoelectric converter, the first electrode of which is connected to one of the electrodes of the second pneumoelectric converter.

The drawing shows the scheme of the proposed integrating device.

The non-motor inverter has an air chamber 1, the casing of which

made of insulating material. In the chamber 1 is made the inlet 2, connected to the input channel of the device. Two metal electrodes are rigidly fixed in chamber 1: anode 3 and cathode 4.

A calibrated cap p 5 connects the air chamber with the air chamber 6 of the second transmution transducer, housing

which is also made of insulating material. Two metal electrodes are rigidly fixed in chamber 6: anode 7 and cathode 8. Anodes 3 and 7 are connected to each other and directly to a source of high power — a generator 9 of sawtooth wavelengths through a load resistor 10, in parallel with which unit 11 is measured. Cathode

8 is connected to the generator 9 sawtooth pulses through a load resistor 12, which is connected in parallel with the block 13 measurement. Integrating device operates as follows.

In the inlet 2 of the air chamber 1

input signal P. is applied. To electrodes 3, 4

through the load resistor 10 from the generator

High-voltage pulses are applied to 9-sawed pulses. At a fixed distance between the electrodes, the voltage across which gas breakdown occurs (including

air), directly depends on

gas pressure in the interelectrode space.

Thus, the amplitude of the current pulses in the circuit of the load resistor 10 will be directly proportional to the pressure P of the input signal. From the load resistor 10, voltage pulses are applied to a measurement unit 11, for which an amplitude or phase detector can be used. Next, the pneumatic signal through the calibrated capillary p 5 enters the air chamber 6, while the pneumatic signal is integrated. High-voltage sawtooth pulses are applied to electrodes 7, 8 through a load resistor 12 from generator 9.

At a fixed distance between the electrodes, the nanorrhion at which the gas reaches the gas is directly proportional to the pressure of the gas in the interelectrode space. Consequently, the amplitude of current pulses in the value of the load resistor 12 will be proportional to the integral of the pneumatic signal pressure in chamber 1. The voltage impulses 12 receive voltage on the measuring unit 13, which can be used as an amplitude or phase detector.

Thus, the electrical signal of the measuring unit 11 is proportional to the function of the pressure of the pneumatic signal, and the electrical signal of the measuring unit 13 of the proportional integral to the pressure function of the same musical signal.
